What you describe means that the software that actually draws to the
glass doesn't do what Emacs tells it to do.

Check the settings of your video hardware -- if there are some
"optimization" features there, turn them off, reboot, and try again.

If that doesn't help, check your versions and configuration of the X
related stuff (Xlib etc.) -- maybe you have some broken version.
